Multiple linux issues when testing production build

[nadr0]

During the cut release process we use this manual check list. I did a cut release with Frank yesterday and ran through the linux checklist and there are several linux issues.

This issue is to list all of the linux problems I saw, we can break this out into individual issues if needed.

• ❗ (Does not work on linux) mod + shift + ., cannot open the coredump feature with this command. It does not work.
• ❗ (Does not work on linux) double click to open files from finder opens new window each time (mac/windows). After installing the production application I could not double click .kcl files in my file explorer and have it automatically open in ZMA.
• The ZMA icon does not appear in the file explorer or toolbar.

I have a partial fix for the icon not showing up in #4554 . I couldn't figure out how to get the icon to show up in the file tree tho

Pretty convinced at this point that the icon comes from free already with electron-builder, but appimaged is needed on the target system for it to be picked up. See comment at #4554 (comment).

Re: the CoreDump hotkeys not working. It's because the key changes when shift is pressed and that causes it to not get picked up by the library.

The maintainer has an issue he commented on a while back: JohannesKlauss/react-hotkeys-hook#1064 that attempts to address it. His patch didn't work when I tried it, but changing the key combination to mod + shift + > or mod + alt + . caused it to get picked up correctly

Checked two boxes in the original description (icon and open with...) are both are now okay. Instructions were written and part of this PR #4592

The coredump one still needs to be addressed.
